CLINICAL AND EXPERIMENTAL STUDY OF PERIPHERAL NERVE REGENERATION.

Late Breaking Abstract - CRAC channel inhibition by RP3128 triggers potent anti-inflammatory effects in COPD or asthmatic patient-derived primary cel…

2018

Introduction: Calcium release activated calcium channels inhibitors have a potent role in treatment of autoimmune disorders. RP3128 is a novel and potent inhibitor of Calcium Release Activated Calcium (CRAC) channel activity with demonstrated efficacy in several models of immune-inflammatory disorders. The objective of this study was to assess the effect of RP3128 and combinations in attenuating inflammatory responses associated with respiratory diseases. Methods: Inhibition of antigen-induced cytokine release in primary T-lymphocytes was estimated. Peripheral blood neutrophils or mononuclear cells were isolated from COPD or asthmatic patients, pre-incubated with RP3128 for 0.5 h, and stimu…

Lipid-lowering therapy use in primary and secondary care in Central and Eastern Europe: DA VINCI observational study.

2021

Abstract Background and aims Central and Eastern Europe (CEE) is a largely understudied region, despite having the highest cardiovascular disease mortality in Europe. This analysis aimed to assess the proportion of patients in CEE who achieved their LDL-C goals based on individual cardiovascular risk recommended by the 2016 and 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines. Methods The DA VINCI study was a cross-sectional observational study of primary and secondary prevention patients receiving lipid-lowering therapy across Europe between June 2017 and November 2018. Results In total, 2154 patients were enrolled from the Czech Republic (n = 509…

Heterogeneous response to differentiation induction with different polar compounds in a clonal rat rhabdomyosarcoma cell line (BA-HAN-1C)

1989

The clonal rat rhabdomyosarcoma cell line BA-HAN-1C was tested for its susceptibility to differentiation induction with different polar compounds. This cell line is composed of proliferating mononuclear tumour cells, some of which spontaneously fuse to form terminally differentiated postmitotic myotube-like giant cells. Exposure of BA-HAN-1C cells to dimethylsulphoxide (DMSO), hexamethylene bisacetamide (HMBA), sodium butyrate (NaBut) and N-monomethylformamide (NMF) resulted in a significant inhibition of proliferation (P less than 0.001) and in a simultaneous increase in differentiation. The response was most pronounced after exposure to NMF as evidenced by a marked increase in the creatin…

From a Better Understanding of the Mechanisms of Action of Histone Deacetylases Inhibitors to the Progress of the Treatment of Malignant Lymphomas an…

2017

Background Notable progress has been made in chemo- and immunotherapy of B-cell lymphomas, but less in the treatment of T-cell lymphomas. Objective Histone deacetylases inhibitors are a potentially useful therapeutic mean, as an epigenetic dysregulation is present in lymphomas, and especially in T-cell types. We aimed to study the progress made in this area. Method A mini-review was achieved using the articles published in PubMed in the last two years and the new patents made in this field. Results Histone deacetylases inhibitors are involved in the derepression of tumor suppressor genes through a histone deacetylase-mediated transcriptional process. Their inhibition is followed by cell cyc…

Cancer stem cell definitions and terminology:the devil is in the details

2012

The cancer stem cell (CSC) concept has important therapeutic implications, but its investigation has been hampered both by a lack of consistency in the terms used for these cells and by how they are defined. Evidence of their heterogeneous origins, frequencies and their genomic, as well as their phenotypic and functional, properties has added to the confusion and has fuelled new ideas and controversies. Participants in The Year 2011 Working Conference on CSCs met to review these issues and to propose a conceptual and practical framework for CSC terminology. More precise reporting of the parameters that are used to identify CSCs and to attribute responses to them is also recommended as key t…

Challenges and new prospects in hepatosplenic γδ T-cell lymphoma.

2014

Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of lymphoid neoplasms characterized by aggressive clinical behavior and dismal prognosis. Hepatosplenic γδ T-cell lymphoma (γδ-HSTL) is a particular form of PTCL that arises from a small subset of γ/δ T-cell receptor-expressing lymphocytes. γδ-HSTL has a rapidly progressive course and poor outcome due also to its refractoriness to conventional chemotherapy regimens. The very low incidence of γδ-HSTL, along with its propensity to mimic different pathological entities, makes this lymphoma a true diagnostic challenge. In this review, we highlight the biological and clinical features of γδ-HSTL that contribute to making this lymphoma…

Cytolytic T cell reactivity against melanoma-associated differentiation antigens in peripheral blood of melanoma patients and healthy individuals

1996

Antigenic peptides derived from several differentiation antigens of the melanocyte lineage were recently identified in human melanomas as targets for HLA-A2.1-restricted cytotoxic T lymphocytes (CTLs). To examine their potential role in tumour-directed immune responses in vivo, we determined CTL reactivity against seven antigenic peptides derived from the Melan A/MART-1, tyrosinase and gp100/Pmel17 antigens in the peripheral blood of 10 HLA-A2+ healthy controls and 26 HLA-A2+ melanoma patients. The influenza matrix peptide (GILGFVFTL) presented by HLA-A2.1 was used as a control peptide. CTL reactivity was assessed in a mixed lymphocyte 'peptide' culture assay. Reactivity against Melan A/MAR…

Blood T-cell Vβ transcriptome in melanoma patients

2004

Tumor-cells have been shown to elicit MHC-restricted and antigen-specific T-cell responses. In this article, we used a new approach to study T-cell responses in tumor-bearing patients based on a global representation of the Vβ-transcriptome, making it possible to grade CDR3-length distribution (CDR3-LD) alterations. Six patients with advanced melanoma disease, from whom blood samples were taken before and serially after tyrosinase-A peptide vaccination, were studied. The PBMC from patients displayed highly significant Vβ transcriptome alterations as compared to healthy individuals. Similar Vβ alterations could be detected both in PBMCs and at the tumor site. After vaccination, Vβ alteration…
